IMPROVED BUMPER-SPRING.

Specification forming part of Letters Patent No. 45,927, dated January17, 1865.

To all whom it may concern:

Be it known that 1, ROBERT LEVINGTON, of Monroe, in the county of Monroeand State of hlichigan, have invented a new and useful improvement inprotecting the bumpersprings and their necessary appliances to rtlll'OEtd'C/kLYS from breaking when the cars strike together; and I dohereby declare that he following is a full and exact descriptiont'lereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

The nature of my invention consists in attaching a protector to the bedof a car-body to serwe as a bumper, and also to protect the spring thatis attached to the draft-bar from any unnecessary strain when the carsrun to gether, all of which is clearly described in the followingspecification.

The accompanying drawing is in perspecti ve,representingits severalparts-viz., beams- A A, ties C and D, stays B B, crossbars H and L,spiral spring M, yokes F F, yoke J, yoke N, protector K, and draw-bar E.

The beams A A, ties G and D, and stays B B are all framed and boltedtogether so they can be fastened to the bed of a car-body in a properposition for the connection to be made from one car to another. Theyokes F F are attached to the beams A A by means of the bolts R R in aposition to receive the end of the crossbars H and L in the slots I I.The forward end of the draw-bar E is attached to the tie D by means ofyoke N, which is attached thereto by means of bolt W. The back end ofthe drawer E has the yoke J attached to it by means of the bolts X X ina position to form a slot through which the cross-bars H and L pass, andin which the spring M is placed between said bars.

I will describe the operation of my protector as follows: \Vhen the carsare in motion, on being suddenly stopped, they strike with great forceagainst each other, thereby forcing the draw-bar E back until the yoke Jstrikes the protector K, at 0, thereby protecting spring M, cross-bar H,and yokes F F from any unnecessary strain, and thereby saving a largeamount of breakage.

After thus having described my invention, what I claim, and desire tosecure by Letters Patent, is

The protector K and the yoke J in combination therewith, as is clearlyset forth and de- Witnesses:
